This grammar point often appears in neutral to formal Japanese. If you want to expand a statement to include additional qualities or facts, だけでなく is a useful pattern to learn.

Nuance of だけでなく
The key nuance is more natural and common in spoken Japanese than ばかりでなく; versatile across registers.
This matters because 〜だけでなく is the everyday alternative to ばかりでなく. It is less formal but equally correct. It pairs naturally with も..
For example:
- In academic writing, it sounds natural and specific.
- Compared with ばかりでなく, it carries a different weight and implication.
だけでなく vs ばかりでなく
Both だけでなく and ばかりでなく can express not only… but also, but they are different.
だけでなく:
- more neutral and common in both spoken and written Japanese; softer tone
ばかりでなく:
- slightly more formal and emphatic; often used in written or intellectual contexts
Quick contrast examples:
- 安いばかりでなく、品質もいい。 \u2014 Not only cheap, but also high quality (formal).
- 安いだけでなく、品質もいい。 \u2014 Not only cheap, but also high quality (natural).
